Kind of surprised you haven't gotten an answer for this by now. There are two simple ways to edit a used map (game save) with any version of Factorio (Steam included).

The first way: Explore to your Steam installation directory. You want Steam\steamapps\common\Factorio\bin\x64. In Windows Explorer, hold the shift key and right-click on the x64 folder and select "open command window here" from the context menu. Type in the command window: Factorio --map2scenario <saved game name without the .zip extension>. So you'd type (ex) Factorio --map2scenario mygame

The command window will show Factorio loading, then a message about creating the scenario map. When it says "goodbye", type 'exit' or close the window.

The second way, if you're not comfortable with command-line arguments, or can't get one to open: Create a new text document. Type into the document: Factorio.exe --map2scenario <save name> Save and close the document. Rename it from "New Document.txt" to "New Document.bat". Place it in the Factorio\bin\x64 folder and double-click it. Note that if you use this method, the command window will close by itself when Factorio is finished creating the scenario map.

Hey targa,thank you so much for the help as ive been searching a way to edit maps as well. However,i tried the first method to edit the map.But after i saved it and closed it, when i load the map its still the same as how it has been before the editing. Was just wondering how do i play the map i edited.
